• curprev 18:4518:45, 16 January 2020‎ >Tomh‎ m 17,159 bytes −3‎ →‎Interrupts: Clarified: this is mainly(/entirely?) the MFP.

15 January 2020

• curprev 19:0519:05, 15 January 2020‎ >Tomh‎ 17,162 bytes −747‎ "Shifter state machine" needs a lot of work, but this otherwise seeks to improve total article flow.
• curprev 14:5414:54, 15 January 2020‎ >Tomh‎ 17,909 bytes −24‎ Pulls horizontal state machines into a common section.
• curprev 14:5114:51, 15 January 2020‎ >Tomh‎ 17,933 bytes +400‎ Reordered to go vertical, then horizontal, then shifter. Added mention of sync interrupt latches.
• curprev 14:4414:44, 15 January 2020‎ >Tomh‎ m 17,533 bytes −4‎ Removed 'necessarily' as the result touted is universal.

2 January 2020

• curprev 18:4118:41, 2 January 2020‎ >Tomh‎ m 17,537 bytes 0‎ →‎Vertical state machine: Corrects table heading.
• curprev 16:0916:09, 2 January 2020‎ >Tomh‎ m 17,537 bytes −126‎ Pulls the vertical state machine section up to the top, rather than having it between the two horizontal state machines and the list of potential horizontal line lengths.

29 December 2019

• curprev 19:5819:58, 29 December 2019‎ >Tomh‎ m 17,663 bytes +2‎ Fixed: incomplete, not complete, obviously.

18 December 2019

• curprev 16:3016:30, 18 December 2019‎ >Tomh‎ m 17,661 bytes 0‎ →‎Horizontal GLUE state machine, ST: Corrects column title.
• curprev 11:2911:29, 18 December 2019‎ >Tomh‎ 17,661 bytes +1,102‎ Attempts a more substantial clean-up of the opening section.

10 December 2019

• curprev 13:2913:29, 10 December 2019‎ >Tomh‎ m 16,559 bytes +984‎ →‎Horizontal GLUE state machine, ST: Reformatted a little for a cleaner read, added some comments on latency.

11 April 2016

• curprev 17:1917:19, 11 April 2016‎ >Troed‎ 15,582 bytes −494‎ Major update for ST and STE GLUE horizontal tables. Previously they were correct for 50Hz lines, now 60Hz also.

16 March 2016

• curprev 19:1519:15, 30 January 2014‎ >Troed‎ 13,146 bytes −89‎ Since my updates have slowed down it's time to stop calling it a draft.

7 October 2013

• curprev 20:0020:00, 7 October 2013‎ >Troed‎ 13,235 bytes +58‎ ST = GLUE+MMU, STE = GST MCU. Also includes hypothesis on how preloading works as well as the new line lengths possible using it.
